Climate change is a major concern for South Floridians. The Broward MPO is working with its partners in the four-county area (Monroe, Miami-Dade, Broward and Palm Beach) to create solutions for the current and future challenges of extreme weather, sea-level rise, and storm surge. In line with the MPO Goals (Move People and Goods, Create Jobs, Strengthen Communities), the Broward MPO is incorporating resiliency into transportation decision-making.
The Commitment 2045 Metropolitan Transportation Plan (MTP) is the result of a two-year collaboration of the MPO, its partners and public input. The Plan lays out a multimodal transportation system from 2020 through 2045 and is a Core Product of the Broward MPO.
The 2045 MTP identified six planning factors to guide the overall MTP development process: Mobility, Accessibility, Safety, Equity, Economic Vitality, and Environmental Stewardship. Resiliency is a key consideration in the MTP’s goals and objectives, needs assessment, and performance monitoring elements.
The 2045 MTP drew from regional partner studies including the Regional Climate Action Plan, the 2015 Compact Unified Sea Level Rise Projection, and the South Florida Climate Change Vulnerability Assessment and Adaptation Pilot Project to identify eight (8) resiliency studies. The 2045 MTP also included a resiliency scenario to test potential future outcomes based on the impact of climate stressors on the region’s roadway network and to help identify projects for inclusion in the MTP's cost feasible plan.
The Broward MPO worked closely with the Florida Department of Transportation (FDOT), District 4 and drew from the South Florida Climate Change Vulnerability Assessment and Adaptation Pilot Project to select and prioritize roadway segments based on their vulnerability to sea-level rise, storm surge, and/or 100-year storm events within the 2045 planning horizon. Based on coordination with FDOT, the team agreed to include these roadway segments as resiliency studies in the cost feasible plan to identify the most appropriate long-term solution for these facilities in conjunction with the MPO’s planning partners.

The 2045 MTP incorporated resiliency in the following sections of the document (refer to page numbers):
- Objective: Promote Resiliency in Response to Climate Change and Weather-Related Events
- Reference: Page 1-3
- Describes the current state of the transportation system in the context of resiliency and recent analyses including the South Florida Climate Change and Vulnerability Adaptation Project which identified discrete roadway segments that would be impacted by 1, 2, and 3 ft. of sea-level rise. The top eight roadway segments impacted by 2 ft. of sea-level rise (projected by 2045 planning horizon) were included as cost feasible resiliency studies in the final MTP project list (see below)
- Reference: Page 3-13
- Scenario planning was used as part of the MTP development to test different future outcomes based on a shift in policy or the impact of stressors. The resiliency scenario used the roadway inundation data (impacted by 2 ft. of sea-level rise) from the South Florida Climate Change and Vulnerability Adaptation Project and assumed any projects on inundated facilities would be removed from the network to test their potential impact on the system.
- Reference: Page 4-5
- Environmental Stewardship was one of six planning factors established to rank and prioritize projects and included the following specific criteria:
- Improvements related to sea-level rise mitigation/extreme weather resiliency
- The Broward MPO Board (along with the Technical and Citizens’ Advisory Committees) participated directly in a poll to establish weights for the six planning factors. Environmental stewardship was weighted 12.8% based on the average of the feedback we received from the MPO Board and Committees
- Draft Technical Report #4 (Project Prioritization Process) also provides more information on the scoring and project scoring process (see page 16 for specific scoring criteria on sea-level rise mitigation/extreme weather resiliency)
- Reference: Page 4-15
- Based on the information from the South Florida Climate Change and Vulnerability Adaptation Project and the Resiliency Scenario, the top 8 roadway segments impacted by 2 ft. of sea-level rise (projected by 2045 planning horizon) were included as cost feasible resiliency studies in the final MTP project list.

- These projects are programmed in the first five-year time band (2026/30) of the plan to identify the appropriate infrastructure project to program in future MTPs based on the outcome of the area-wide study. These studies will focus on the type and extent of the inundation the facility is expected to experience and how this will impact the surrounding roadway network. This will help develop a more comprehensive capital outlay of projects to properly address the potential risk

South Florida Climate Change Vulnerability and Adaptation Pilot Project
The Broward MPO led the Pilot Project to examine the vulnerability of the regional transportation network to climate stressors in the four-county South Florida region.
The Pilot Project covered the four counties and three MPOs in the South Florida area. The purpose of the Pilot Project was to determine the impact of extreme weather on the area's regional transportation network based on the following stressors:
- Sea level rise
- Storm surge
- Precipitation-induced flooding
The focus of the Pilot Project was to develop a consistent methodology for integrating vulnerability into the MPO transportation decision-making process. The Broward MPO Board endorsed the South Florida Climate Change Vulnerability and Adaptation Pilot Project on March 12, 2015 and the Federal Highway Administration approved it on September 29, 2015.
Extreme Weather and Climate Change Risk to the Transportation System in Broward County, Florida Study

The Second Phase of the Pilot Project applied the climate change stressors to county and local roadways within the Broward region.
On December 11, 2014, the Broward MPO authorized the funding of the Second Phase Study, building upon the work of the Pilot Project. This Second Phase Study applied the climate change stressors to county and local roadways classified as collectors and above within the Broward region. This effort included an assessment of the locations and elevations of significant roadways and bridges throughout Broward as compared to current and future flood levels.
The analysis resulted in the identification of vulnerable facilities and methods for treatment of the impact of specific stressors on the roadways. The Second Phase Study provided planning level cost estimates for these treatments and recommended strategic approaches for decision-makers to determine where to focus on transportation investments. The MPO Board approved the Second Phase Study on October 13, 2016.

The Broward MPO hosted All-Hazards Recovery Training, an FTA-sponsored program, on March 5-6, 2018.
The purpose of this training was to equip the region to develop a comprehensive emergency recovery plan that maximizes the use of transit, social media, TDM strategies, and ITS technologies.
Sea Level Rise (SLR) Viewer Training- October 27, 2017.
The Broward MPO hosted a Sea Level Scenario Sketch Planning Tool technical training workshop provided by the University of Florida GeoPlan Center on October 27, 2017. The Florida Department of Transportation (FDOT) sponsored the training, including information on SLR projections, as well as demonstrations of the tool, guided training exercises, and a group exercise.
